home defense and Verney-Carron Flash-Ball

[u/Careful_Passage969]

i was wondering with the violence increasing (i am in montreal, people break in houses is increasing) why Verney-Carron Flash-Ball is not allowed?

I check the law and I saw the joules etc but can we decrease the PSI of it? I know they're mostly associated with law enforcement in some countries.

just wondering if a company had release a news for an equivalent.

Edit: for **self-defense**

in canada self defense using a firearm is illegal because they dont want us to protect ourselves
